Allow users to modify or unsubscribe from subscriptions created on their behalf by other people

[jmilton]

Subscriptions have come a long way but one thing that would be helpful is to allow users to see and edit their subscriptions that are created by other users. As it stands now users have to contact the person who created the subscription on their behalf to have it modified or to be removed from the subscription.

Love the new self subscribe feature, but we really need to allow more flexibility.  Agree whole heartidly with this one!!!
